DH has reneged on post nup he had promised (pre marriage) he would enter into to protect family inheritance

Before we got married c 8 years ago, I had said to my DH (financè at the time) that I’d want a pre nup to protect a significant family business, and other inherited assets, that would likely be passed down to me. The value of the inheritance will be significant and so with my sensible hat on I am keen to protect that in any way I can.

For a number of reasons that prenup wasn’t entered into before we married, but he discussed with my Dad and gave him his word (and he did likewise with me) that he’d enter into it in future before any interest passed to me as part of the family’s estate planning. This has been looming a while but we are now at the time where this needs sorting. I have tried and tried to speak to my DH but he is always busy (though I am the main breadwinner, by some way…), explains his fear that I’ll take the family house off him (the post nup leaves the entire family home to him exclusively - valued at £900k and minimal mortgage) and leaves me with a small property rental and ensures that any interest in the family’s wealth remains my asset).

He is so apprehensive about entering into it that he called my dad outright a couple of weeks ago and asked him what he was expecting my DH to do. This is something I’m driving because (a) we are in a bad place and have been for a few years and (b) I can’t bury my head any more and need this sorted. My father was cross at the phone call as he was caught off guard, and on reflection why such reluctance now to discuss with Dad - when he left it years ago on the basis he’d sign something.

He won’t discuss it with me, when I go into his office at night to ask whether he will engage with me on it he tells me to get out, he is exhausted and doesn’t have time to talk about it let alone look for a solicitor that will advise him on it (I’ll pay all of those fees) and ends up putting noise cancelling headphones on with music blaring until I go out. If I stay there he says that he will lock his office door so he is left in peace.

I am at my wits end and had always said to myself that I can put up with his treatment at home (the above being an example) but am so concerned that this is the final nail in the coffin of my marriage (3 young DC under 7, one of which is extremely anxious and constantly worried so I don’t know what a separation would do to her).

If I were to bring our divorce papers I am almost certain he would start to engage - but what concerns me is these post nups are only valid for 5 years and need to be kept under review every 5 years. If he won’t engage now then god help me in 5 years’ time again.

Please be kind as I am worried sick but appreciate any advice. I’ve even considered initiating a divorce for purely financial separation whilst continuing to live long term under the same roof - I am willing to give the marriage everything I have got but the financial worry I am carrying is killing me. I think he expects that he will fail to engage and it will all go away because I’ll get bored of chasing him but fundamentally this is such a U turn from what he promised me before we got married that I am not sure I could ever get over it.

I'm not sure prenups or postnups stand in UK law, particularly in a relatively long marriage with children. Before causing a huge row I would talk to a lawyer, but without his consent in writing I'm pretty sure there is nothing you can do, a verbal promise probably doesn't count as a contract.

If you haven't inherited it yet, how can he have a claim, if you divorce now?

Yes, decorating their rooms in your existing home would be mad. especially as your soon-to-be-ex may well have to sell the place at some point in the next year, after you've moved out.

Your insistence that the future arrangement must be 50:50 also comes across as a bit crazy. From everything you've said, he has never - at any point in the lives of your 3 children - done anything like 50% of the work required in raising them. What makes you think that he'll magically step up and become a competent, reliable parent now?

Far better to (as they say on MN) "get your ducks in a row" and collate all the evidence you'll be able to use to prove that you are their main carer, that you've been responsible for organising pretty much every aspect of their lives (everything from dealing with the school to taking them to the dentist to buying them new shoes/clothes to cooking every single meal they eat...)

Any decent lawyer would easily be able to ensure you get close to full custody. It really doesn't sound like their father will ever really prioritise the needs of the DC over his job/ personal lifestyle.

I can see that you're keen to bend over backwards so he can't complain about you treating him unfairly. But be assured - he will doubtless complain (to your DD, to his parents, to his work colleagues, to any woman unfortunate enough to date him in future.. basically, to anyone who'll listen!) of unfairness whatever you do or don't do at this stage. He is a selfish, over-entitled, disrespectful jerk.

He does not deserve any more from you!
Your children will survive this! They'll probably thank you in years to come, when they fully understand what a wastrel their father is, and how much you've done for them.

PS: I was horrified to read your updates about how much he's been spending on things like the car, the patio-renovation etc and that he's set up a surveillance system to keep an eye on you and your movements 24 hours a day (don't kid yourself it's for security purposes - if it was he'd have made sure you had access to the footage). You could put black electrical tape over the cameras/ movement sensers.

Forgot to say - also, please don't buy new washing machines etc for him, not even 'cheap' ones. Either get second-hand ones, or let him go to the bloody launderette/ put his hand in his own pocket.
